GRAIN-BINDING HARVESTER.

FlT-CLFICATION forming part of Letters Patent No. 340,096, dated April 20, 1886.

Application filed March 28, 1884.

To @ZZ whom, it may concern:

Be it known that l, CHAnLns CoLllHAN, of Cleveland ,Cuyahoga county,and State of Ohio, have invented certain new and useful Improvements in Grain-Binding Harvesters Operated in Connection with Grain-Binders; and I do hereby declare that the following` is a full, clear, and exact description of the same, reference being made to the accompanying drawings, forming a part of this specification, in which- Figure l represents a sectional view of the harvester, showing the binder mounted thereon in its normal position of receiving thegrain as it is being cut and delivered to the binding receptacle, Where it is bound in the usual mannerin the rear ofthe main drive or supporting wheel of the harvester, the outer end of the platform being supported on a grain-wheel of the usual form. Fig. 2 represents the machine as seen while in the process of binding a sheaf'.

Hy invention relates to certain improvements in construction and arrangement of the grain-delivery apparatus operated in combination With a binder and its supplemental rake or packing arms in such a manner as to dispense with intermediate ordinary elevating mechanism, thus simplifying the machine and obviating the liability of shelling or thrashing out the graimwhich is a great loss in the process of harvesting, the grain being wasted and scattered on the field in the violent raking, jarring, and agit-ating of the ripe heads of heavy grain, as in the old machines, thus making simplicity of construction and adaptation of devices to practical use an important invention.

In the accompanying drawings, A represents the main frame of the harvesteig. W, the main wheel; B, the continuously-revolving carrier located behind the cutting-bar, and on which the cut grain falls and is carried forward to the receiver or delivery end thereof, and C a supplemental revolving apron, which is adjustable, and also has the capacity of yielding to admit of the delivery of accumulated masses of lodged grain without liability of obstruction in the operation of forcing the grain forward between the rollers of the tWo aprons, which form a moving and deflectingsurface to the rollers, and thus pressing the grain for- Serial No. 123,929. (No model.)

ward into the receiver and causing it to rise in the reach of the packing-fingers of the binder, where it is formed and bound in bundles of uniform size in the usual manner.

E represents a vibrating slatted platform consisting of straight or slightly-curved teeth or slats or a plain smooth surface, the same being secured to a rock-shaft, e, attached to the binder-table, and on which it vibrates intermittently as the binder-arm advances and recedes in the operation of binding, said vibrating platform being depressed by the force or pressure ofthe infiowing grain when the binder-arm is encircling the grain on the bindertable during the formation of a bundle, and when the binderarm recedes beneath thetable a lug, e, on one side of the binder-arm G will be brought in contact with a crank, E', which is secured to the rock-shaft e', and cause the slatted platform to rise in the receiver, and the grain accumulated therein will be forced forward by the action of the continuously-re volving carrier B and supplemental apron C, as it passes between their rollers to the bindertable, where the packers F will gather it to the binder.

Thus it will be seen that the general construction and operation of the harvester are of the common form, While I dispense with the ordinary elevators and deliver the cut grain into an intermittently contracting and expanding receiver, and force it therefrom at proper intervals by the operation of the carrier and supplemental aprons and their rollers, which, in con nectiou with the inflowing grain and the operation of the vibrating slatted platform, never fails to force the grain to the packerarms, and thus to the binder, While the vibrating slatted platform will alternately diminish and increase the capacity ofthe receiver, which in some conditions of grain is important; and 4a machine so constructed requires less breadth of binder-table, and is consequently more compact, while the slattcd platform aids to guide and deliver the grain to the binder.

The upright apron is made readily adjustable.

D represents the receiver.

E is the slotted platform or falling vibrating ngers.

The harvester has the usual convenience of IOO raising and lowering and tilting on the main axle. (Not shown here.)

Having thus described my invention,what I claim, and desire to secure by Letters Patent, 1s-` l.' In combination with the carrier-apron B, the adjustable apron C, the receiver D, and the binder arm G, operating substantially as shown and described.

2. The combination of the apron B, the adjustable apron C, and the receiver D, provided with an independent device and means for raising and lowering the same to contract and expand the receiver, so as to permit an accumulation of grain in the receiver during the binding operation, as 'and for the purposes specified.

3. The aprons B G, the receiver D, the alternately rising and falling fingers E, combined with the binder-arm G, and therpackers F F, constructed and operating substantially asset forth.

4. The combination, with a harvester and binder, of the receptacle D, provided with the 5. The combination of the apron B, the forc-V ing apron C, and the receiver D, provided with an independent device and means for raising the same to aid in guiding the grain to y the binder during the formation of the bundle, and for lowering the same during the binding operation to enlarge the receptacle, so as toy permit an accumulation of grain during the binding operation, substantially as and for the purposes specified.

6. The concave receptacle D, combined with the forcing-apron@ the vibra-ting fingers E, and the binder packing-arms F F, constructed and operating substantially as shown and described.
